Shaacinta u nuglaanshaha kale ee soo-saareyaasha Intel, ee loo yaqaan MDS (ama Zombieload), waxay u adeegtay dardar-gelin kale oo dood ah oo ku saabsan inta isticmaalayaasha hoos u dhigaya waxqabadka ay u dulqaadan doonaan haddii ay rabaan inay ka faa'iidaystaan ββhagaajinta la soo jeediyay dhibaatooyinka hardware. Intel ayaa daabacday iyada , kaas oo muujiyay saamaynta waxqabadka aad u yar ee hagaajinta xitaa marka Hyper-threading la naafo yahay. Si kastaba ha ahaatee, qof kastaa kuma raacsana jagadan. Shabakadda Phoronix waxay qabatay madax-bannaanideeda dhibaatooyinka Linux, oo ay ogaadeen in codsanaya hagaajinta ee dhammaan set ee dayacanka Processor ee la aqoonsaday dhawaan ay keento hoos u dhac ku yimaada waxqabadka processor-yada Intel celcelis ahaan 16% iyada oo aan la curyaamin Hyper-threading iyo 25% iyada oo naafo ah. Isla mar ahaantaana, waxqabadka processor-yaasha AMD ee leh qaab dhismeedka Zen +, sida lagu muujiyey tijaabooyin isku mid ah, wuxuu hoos u dhacayaa kaliya 3%.
Imtixaannada lagu soo bandhigay daraasadda, waxaan ku soo gabagabeyn karnaa in hoos u dhaca waxqabadka processor-yada Intel uu aad ugu kala duwan yahay codsiga iyo, marka Hyper-stringing uu naafada yahay, waxay si fudud u dhaafi kartaa xitaa hal jeer iyo badh cabbirka. Dhab ahaantii, tani waa dhab ahaan waxa aan ka hadlayno Apple, marka ay magacawday qiimihiisu baabi'inta Zombieload - ilaa 40%. Isla mar ahaantaana, Apple, sida Google, ayaa sheegay in tani ay tahay habka kaliya ee lagu samayn karo nidaamyada ku salaysan processor-yada Intel gebi ahaanba ammaan ah. Haddii aadan damin Hyper-stringing, hoos u dhaca waxqabadka wuxuu sidoo kale noqon karaa mid la dareemi karo: kiiska ugu xun, wuxuu gaaraa laba jeer cabbirka.
Waa in la caddeeyo in imtixaanada Phoronix ay ka walaacsan yihiin hubinta saamaynta dhammaan balastarrada ka dhanka ah dhammaan dayacanka dhow - Specter, Meltdown, L1TF iyo MDS. Tani waxay ka dhigan tahay in kiiskan aan ka hadlayno farqiga ugu sarreeya ee waxqabadka ee milkiilayaasha Intel Processor-yada ay heli doonaan ka dib marka la isticmaalo dhammaan balastarrada hal mar. Tani waxay sidoo kale sharraxaysaa hoos u dhaca waxqabadka lagu ogaaday soo-saareyaasha AMD. In kasta oo MDS aysan saameyn ku yeelan iyaga, chips-yada AMD waxay u nuglaadaan noocyada qaar ka mid ah dayacanka Specter oo sidaas darteed waxay sidoo kale u baahan yihiin dhejisyada software. Si kastaba ha ahaatee, uma baahna wax tallaabo ah oo adag sida curyaaminta Hyper-stringing.
Hoos-u-dhac weyn oo ku yimaadda waxqabadka soo-saareyaasha Intel ka dib marka la isticmaalo balastarrada waxay noqon kartaa arrin halis u ah booska shirkadda ee suuqa server-ka. Iyadoo AMD ay isku diyaarinayso inay kor u qaaddo bar-qabadkeeda cusub ee 7nm EPYC (Rome), waxqabadka chip Intel wuxuu si joogto ah ugu socdaa jihada ka soo horjeeda. Isla mar ahaantaana, suurtagal maaha in la diido in la hagaajiyo nuglaanta xalalka server-ka - taasi waa meesha ay ka keenaan khatarta ugu weyn. Sidaa darteed, AMD waxay haysataa fursad ay ugu dhakhsaha badan u noqoto alaab-qeybiyaha xalalka server-ka degdega ah, taas oo saameyn weyn ku yeelan doonta booska ay ku leedahay suuqa server-ka, taas oo shirkadu ay doonayso inay ku hesho 10 boqolkiiba sanadka soo socda.
Isticmaalayaasha nidaamyada macaamiisha macaamiisha ayaa laga yaabaa inay si fiican u diidaan isticmaalka balastarrada, ugu yaraan ilaa laga ogaado xaaladaha ka faa'iidaysiga khatarta ah ee dayacanka. Si kastaba ha noqotee, marka loo eego tijaabooyinka Phoronix, halka Core i7-8700K asalka ah uu ka dhakhso badan yahay Ryzen 7 2700X celcelis ahaan 24%, ka dib marka la codsado hagaajinta faa'iidada ayaa hoos loo dhigay 7%. Haddii aad raacdo talooyinka ugu muhiimsan oo, marka lagu daro, joojiso Hyper-stringing, markaa processor-ka AMD ee da'da weyn ayaa ka dhaqso badan doona Core i7-8700K 4%.
